Heat sinks with folded fins offers many advantages. They have the maximum surface area in the minimum space, thus offering better thermal performance. Folded fins are available in a wide variety of material with various fin densities. Folded fins can be attached with their base material with either thermally conductive epoxy or by dip brazing technology to reduce the thermal resistance & improve mechanical integrity
Folded fin heatsinks are generally made from aluminum and/or copper alloys, although other materials can be used. One advantage to this is that heatsink bases thicknesses can be made of thinner.
With folded fin heatsinks, base and fin materials can be mixed in order to tailor thermals to a customer's needs. Either a thermally conductive bonding adhesive or soldering can be used to attach fins to base material. See additional info for manufacturing specifications.
